Traditional auteur criticism, developed in the journal Cahiers du cinéma in the 1950-60s. (see Hillier 1985; 1986) and by Andrew Sarris (1962; 1968, privileged the director's individual subjectivity: their intuition, spontaneous creativity, and personal expression. The distinctive properties that define an auteurist's films are thought to be located in a purely personal or subjective vision, ineffable 'sensibility', or obscure 'interior" meaning. Auteur critics also value the unity of style and themes that a director is able to impose on his or her films. That is, the auteur critic seeks to identify throughout the same director's corpus (whatever the genres involved) a pattern of thematic preoccupations and similarities in visual style. One of the most important aspects of an auteur analysis therefore involves analysing an individual film's style and themes within the context of a director's entire output. (Some auteur critics reserve the term metteur en scene for a director who only maintain consistency in style across their films.)
